Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 80mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30B
The ACQJ80X80-30B is a double-acting JIS compact cylinder featuring an external M20x1.5 threaded stop with a lock nut. This mechanism lets you fine-tune the extend end position on the machine, providing a usable outward range of 50-80mm from the 80mm full stroke, while the retract stroke remains completely unaffected.
Output force stays identical to a standard ACQ of the same bore, giving 2513.2N push and 2267.8N pull at 0.5MPa. It features a 25mm piston rod with a male M22x1.5 thread for direct load coupling, a PT3/8 port, and fixed NBR elastomer bumpers at both ends for end-of-travel deceleration.

Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; the piston area — and therefore the force — is the same as a standard ACQ of this bore. Adjustable window options: 10/20/30/40/50/75/100 mm.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
Force equals a standard ACQ of the same bore — the adjuster changes stroke length, not piston area. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30B Is Used
Machining Fixture Stops
Dial in the exact 50-80mm extend reach on a CNC lathe loader to accommodate raw material length variations without machining custom stop collars.
Assembly Line Changeover
Quickly alter the extended pushing position during product family transitions on a conveyor line, using the external lock nut to set a new end point.
Carton Forming Trials
Test and set the optimum folding flap end position on a packaging machine, tweaking the stroke within the 30mm window until the fold is perfect.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30B the Right Cylinder?
If 2513.2N push at 0.5MPa is excessive, stepping down to a 63mm bore yields 1558.6N; conversely, a 100mm bore provides 3927.0N if more power is required. When the exact 80mm extend position is permanently fixed and never varies between changeovers, a standard non-adjustable ACQ cylinder is the simpler choice. To order this unit correctly, confirm the 80mm bore, 80mm full stroke, 30mm adjuster window, the male M22x1.5 rod option (-B), and PT3/8 porting.
Quick checklist
- ✓ Need on-machine end-position tuning?
- ✓ Full stroke and adjust window (mm)
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the adjuster nut after setting the stop.
- check The stop limits the EXTEND stroke only.
- check Avoid side load on the short piston rod.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30B FAQ
The usable extend range is 50-80mm (80mm full stroke minus the 30mm window). Force is identical to a standard ACQ: 2513.2N push and 2267.8N pull at 0.5MPa, 3518.5N push at 0.7MPa, and a maximum push of 513kgf at 1.0MPa. The retract stroke remains fixed at 80mm.
An external M20x1.5 threaded stop with a lock nut mechanically limits the outward extension, changing only the stroke length and not the piston area, so force is unchanged. Fixed NBR bumpers decelerate the rod at both ends, but this plain cylinder will drift and lose its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
